That’s a pretty simple rule but allows lots of deliberate ways to significantly reduce one group.

You have however written a thing here that’s fine - it’s totally fine if your advert is seen more by men. But what you want, and what we as a society generally want, is for those ads to be shown to likely candidates regardless of gender. Given two equally qualified people, do you want your ads to only be shown to one of them, because the other is a woman? I assume not because you want to hire th best person not the best man.

The issue isn’t that the ads are shown to more men because they target things like “has said they have worked as a mechanic and are looking for a job” and that happens to be more for men, the accusations is that Facebook is specifically using your gender to determine what job adverts to show you.
